Final answer:
Yes, the sender's address and the return address are the same in a business letter. They denote where a reply should be sent, and their proper placement is at the top or after the signature at the bottom of the letter.
Step-by-step explanation:
In a business letter the sender's address is the address of the individual writing the letter, which is also the address to which the recipient would send a reply if necessary, making it the return address as well.
This address is placed at the top of the business letter or after the signature and name at the end of the letter. The proper format of a business letter includes the sender's address, the date, the recipient's inside address, a greeting, the body of the letter, the closing, and the sender's typed name and signature.
Writing a business letter usually involves following a block formatting style, where all the elements are left-justified, the text is single-spaced, and there is a double space between paragraphs.
Aspects like the date, inside address, greeting, body, and closing are essential components of a business letter. To ensure clarity and a professional tone, use a business font such as Times New Roman or Arial, size 11-12.
